    Abstract:

    Improved coke and sinter quality have facilitated an intensification of the blast furnace (BF) operation due to higher gas top pressure, blast rate and blast oxygen content, as well as the flow rate of injected fuel. Specific BF productivity has increased 15-30% accompanied by a reduction in fuel rate. The increased gas intensity of melting has facilitated faster indirect wustite reduction without any negative impact on the reduction efficiency.
